I have had this error message several times since using Celestia:
"Runtime error !
this application has request the Runtime to terminate it in a unsual way"
This often happens after Windows updates.
And here is what I managed to do to unblock the situation
You can run the DISM tool to scan your Windows system (which will rule out a corrupted system).
To do this:
1. Right-click on Start and select Command Prompt (Admin).
(In Windows 11, press Windows key + Q, type CMD and press Shift + Ctrl + Enter,
or Windows key + "X" and click "Command Prompt (Admin)")
2. Type the following commands. Press Enter after each command:
DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Checkhealth
DISM.exe /Online /Cleanup-image /Restorehealth
I also recommend running the SFC scan, which identifies corrupted files and repairs them automatically.
To run the SFC /SCANNOW command in Windows 10:
Right-click on the Start menu. Left-click on Command Prompt (Admin), which will allow you to launch the tool with administrator rights.
The Command Prompt window will appear.
Type: SFC /SCANNOW and press Enter.
Finally, restart your PC.
Runtime error !

I've always installed in
C:\Program Files\Celestia 1.6.4 for 64-bit (1.6.4)
and C:\Program Files (x86)\Celestia 1.6.1 for 32-bit (1.6.1).
All common files and those that can be moved with modifications to celestia.cfg are in a Celestia Add folder on another drive (.dat, extras, lua-applications, etc., and everything else I use for both versions).
I've never noticed any problems because of this.
Now, what I explained in the previous post is not exclusive. Other reasons can trigger the Runtime error, including errors in the ssc, stc, dcs, and lua files.
After checking your addon files, check your system files. If you're copying and pasting add-ons, be aware that invisible HTML characters can disrupt your work. We've already seen this with 'Croc', where invisible characters in text editors were appearing in Excel.
